Problem with "past.types" from "future" lib on Android and LibreELEC
#1
I adapt my addon for compatibility with 2/3 python using "future" lib. At the Windows addon works correct, but on Android (KODI 17.6) addon throw an exception:

Is there any way to fix this problem?

@vl_maksime

Please try to provide log files via text upload websites like pastebin.com or paste.ubuntu.com (for the larger log files). It will unburden our forum database. Thanks in advance.

Also, your log files appear to be incomplete. Always enable debugging mode in Kodi, and provide the FULL unabbreviated kodi.log, and not those sections that you perhaps find interesting. Errors/bugs can start at any moment. Now there are 3 separate posts, and still there is no full log file AFAICT.

There was link on full log in second post. Updated the rest of the posts, added log files.
I provided part of the log with system information and part where my addon was crashed.

There are 2 independent issues here:
1) Python 2.7 on LibreElec is missing lib2to3 Standard Lib package competely.
2) Python on Android cannot read Grammar.txt file for some reason, although it is present there along with lib2to3 package.

For now I'd recommend not to use "past" package from script.module.future. If you need some features from there, use workarounds. For example:
python:
try:
    basestring
except NameError:
    basestring = str  #For Python 3
